grill valves must be in the off position when the tank
valve is turned on. Turn tank on slowly to allow pressure
to equalize. See lighting instructions.

15 minutes.
Ensure sear plates are installed with the holes towards
the front and the slots on the bottom. See assembly

hardened grease, which dries into paint-like shards,

five minutes or until the ceramic tiles are evenly
glowing red.

covered by objects or accessories. Turn burner off and
allow to cool for at least two minutes, then relight.
